We review, and extend, one of the classic dynamic models of conflict in economics by Richardson (1919) and Boulding (1962). Restrictions on parameters are relaxed to account for alliances and for peace-keeping, yielding new dynamic patterns of conflict. In addition, we explore an incrementalist...

We review, and extend, one of the classic dynamic models of conflict in economics by Richardson (1919) and Boulding (1962). It turns out that the stability properties of the model change if one takes a more realistic “incrementalist” view, and that chance / friction can easily be...

We take issue with the argument expounded, among others, by Layard (2006, Economic Journal) that status-seeking preferences justify heavier taxation of income because this serves to internalise the negative externality that the pursuit of status imposes on others. In a model where status depends...

We introduce public signals and cognitive dissonance into the standard Allingham-Sandmo-Yitzhaki (ASY) model of tax evasion. It turns out that the pres- ence of cognitive dissonanceattenuates tax evasion as individuals dislike allowing their true bevhaviour to diverge from their public statement...

Using examples for each type of model, we consider dynamic games, differential games, and simulation as alternative ways of extending the standard static economic model of conflict to study patterns of conflict dynamics. It turns out that computational requirements and theoretical difficulties...

Wir illustrieren den Einsatz von Simulationstechniken zur Betrachtung komplexer Dynamiken in asymmetrischen Konfliktsituationen mit begrenzt rationalen Akteuren. Dazu wird erst ein formaler Modellrahmen entwickelt, dessen Steady state wir bestimmen. Darauf baut eine Umsetzung des Modells in...

Der Beitrag vermittelt einem wissenschaftlich gebildeten Publikum diesseits der medienüblichen Virologinnen den Mechanismus epidemiologischer Modelle. Daneben wird die Politik in einem epidemiologischen Standardmodell endogenisiert und die zentrale Hypothese anhand von RKI-Daten überprüft. Es...
